The Moon and Saturn will make a close approach, passing within a mere 40.2 arcminutes of each other. From some parts of the world, the Moon will pass in front of Saturn, creating a lunar occultation. The Moon will be 17 days old.

From Fairfield , the pair will be visible in the morning sky, becoming accessible around 22:11, when they reach an altitude of 10° above your south-eastern horizon. They will then reach their highest point in the sky at 01:59, 30° above your southern horizon. They will be lost to dawn twilight around 05:01, 16° above your south-western horizon.

The Moon will be at mag -12.7; and Saturn will be at mag 0.2. Both objects will lie in the constellation Capricornus.

They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 20h48m10s 17°51'S Capricornus -12.7 32'30"1
Saturn 20h48m40s 18°31'S Capricornus 0.2 18"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 166° from the Sun, which is in Gemini at this time of year.
